RIVETING-MACHINE.

Application filed August 3,

To all whom t't may concern:

' Be it known that I, OLIVER C. PENDLETON, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain Improvements in Riveting-Machines, of which thefollowing is a specification.

My invention relates generally to riveting machines, and as herein embodied is designed to produce a machine of this class in which the work is assembled and held in clamped relation during the subsequent operation of heading up the rivets, which is ordinarily done by hand. Such a machine is adapted particularly for sheet metal or other light Work and consists essentially of means for holding and spacing a series of rivets in definite relation, together with a series of anvils arranged adjacent to the rivet holders and requisite work clamping devices coperating with the anvils.

The accompanying drawings will serve to illustrate mechanism suitable for carrying my invention into effect. I do not wish to be understood, however, as limiting myself to either the exact construction or arrangement of parts shown, as various changes may be made therein, without departing from the spirit ,and scope of my invention.

In the drawings, Figure l is a view in front. elevation of a machine constructed in accordance with my invention, the lower portion of the table or bench, the foot treadle etc. being broken away. Fig. 2 is a side view thereof. Fig. 3 is a detail cross sectional view of the arm or support for the rivet holders. Fig. 4 '1s a detail plan view thereof. Fig. 5 is a detail perspective view of the work clamping device and Fig. 6 is a detail view of a portion of the bar carrying the rivet holders.

Referring now to the drawings, I represents a table, bench or other support, upon which is mounted a right angular arm 2, preferably of cast iron. The horizontally disposed portion of the arm is grooved, asA indicated at 3, to receive a bar 4, preferably of steel. Thel bar 4, completely lls the groove, being flush with the upper surface of the arm, as shown, and is cut away at equi-spaced points to provide a series of depressions 5, in each of which a spring clip 6, is secured. The clips 6, are provided at their free ends with notches 7 to receive the rivets 8, which are placed therein with their heads under the clips and the shanks thereof projecting upward through the notches.

The high portions 9 of the bar between the rivet holders, lserve as anvils and coperating therewith there are a series of work clamping devices in the form of notched guide fingers l0, carried by a common support 1I, which is trunnioned in bearings l2, or may be otherwise mounted, if desired. The support 10 is given motion by means of a foot treadle 13, which is connected therewith by rods 14. A retractilespring 15, secured Specification of Letters Patent.

opposite end to the treadle, acts through the rods 14,

to normally hold the work clamping devices elevated, y

as shown in full lines in Figs. l and 2.

The operation of the machine is as follows: In making up sheet metal piping for example, blankscut to a definite size are rst punched to provide a series of spaced rivet holes along opposite edges thereof and are then bent up into cylindrical form with the punched edges overlapping and the openings therein registering. The pipe sections thus blanked and formed, are completed in the riveting machine in the following mannera The sections are slipped upon the arm 2, as indicated by dotted lines in Fig. 2, and adjusted as required to bring the openings therein in line with the rivets, the shanks of which by a slight pressure, are forced through the same. Thus assembled, a slight endwise movement of the pipe section serves to shift the rivets on to the anvils and the operator by pressing upon the treadle brings the clamping devices into action, with `the notched ends thereof in line with the projecting rivet shanks. The rivtes are then headed up in the usual manner by means of a suitable tool and hammer.

I may dispense with the preliminary punching of the blanks and force the riv'ets through the metal after assembling and clamping the section in the machine by the Erst blow of the hammer in upsetting the heads. I have found, however, that this method, while effecting a slight saving in time and labor, does not produce good results as it tends to distort the metal' and open the joint.

Having, therefore, described my invention, I claim:

1. A riveting machine comprising a support having a series of depressions formed therein, and a rivet holder in each depression.

2. A riveting machine comprising a supporting bar having a series of depressions formed therein, a rivet holder in each depression, and a co-operating Work clamping device.l

3. A riveting machine comprising a channeled support, a bar fitted in the channel thereof and having a series of depressions formed therein, and a rivet holder in each depression. l

4. A riveting machine comprising a channeledl support, a bar fitted in the channel thereof and having a series otv depressions formed therein, a rivet holder in each 'idepression, and a co-operating Work clamping device.

5. A riveting machine comprising a support having a series of depressions formed therein, a rivet holder in each depression, a series of Work clamping ngers, a support common to the several fingers, and means for giving the supportlmotion to move the fingers into and out of clamping relation with the Work.

6. A riveting machine comprising a supporting bar having a series of depressions formed therein, a rivet holding clip in each depression, a series of Work clamping fingers, a support common to the several lingers, and

comprising a supporting bar depressions alternating with a ing inclined upwardly and merging into the raised anvil portions, and a rivet holding clip in each depression.

10'. A riveting machine comprising a support having a series of depressions formed therein, and a separate and independent rivet holding device in each depression,

11. A riveting machine comprising a support having a series of depressions formed therein, and a device in each depression for holding a rivet to permit free movement thereof in one direction only.

12. A riveting machine comprising :t support having a series of depressions formed therein, :1nd a fixed rivet holder in each depression.

13. A riveting machine comprising a support having :L series of depressions formed therein, and means xed in each depression for vicldingly holding a rivet.

14. A riveting machine comprising :i support having :i series of depressions formed therein, a series of separate and independent rivet holders, :1nd means for securing a rivet holder in each depression.

In testimony whereof, I ailix my signature, in the presence of two witnesses.
